“…Cd(TFSA) 2 was prepared as described earlier. 24 BMITFSA (Kanto Chemical) and BMICl (Kanto Chemical) were used as received. The electrolyte containing CdCl 2 in BMICl/ BMITFSA was prepared in the same way as BMPTFSA.…”

“…The coordination environment of Cd(II) in several ILs has been reported in literature. 19,21,24,29 was expected to from also in the TFSA ¹ -beased IL. Figure 1 shows the Raman spectra of 0.6 M BMPCl/BMPTFSA with and without 0.2 M CdCl 2 .…”

“…The reduction potential of [CdCl 4 ] 2¹ was more negative than that of Cd(II), which was considered to be [Cd(TFSA) 3 ] ¹ , in BMPTFSA without free Cl ¹ . 24 The formal potential for [Cd(TFSA) 3 ] ¹ /Cd in BMPTFSA without free Cl ¹ was also determined to be ¹0.71 V from the OCP of a Cd electrode in BMPTFSA containing Cd(TFSA) 2 at different concentrations, as shown in Fig. 5.…”

“…Recently, we demonstrated the electrochemical behavior of Cd in BMPTFSA using Cd(TFSA) 2 as the source of Cd species. 24 However, Cd(TFSA) 2 is not always suitable for practical applications because Cd(TFSA) 2 is unavailable commercially. Thus, it is expected that a more common cadmium salt, CdCl 2 , can be used as the Cd source by adding BMPCl into BMPTFSA, as reported in basic chloroaluminate/zincate ILs while there's no report on the electrochemical behavior of the chlorocomplex of Cd in BMPTFSA.…”

Electrodeposition of cadmium (Cd) was investigated in a hydrophobic room-temperature ionic liquid, 1-butyl-1methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) using CdCl 2 as the source of Cd species in the presence of excess chloride ion. Raman spectroscopy and potentiometric measurement suggested formation of a cadmium tetrachlocomplex, [CdCl 4 ] 2− , in BMPCl/BMPTFSA. Cyclic voltammetry showed the possibility of electrochemical reduction from [CdCl 4 ] 2− to Cd(0) with interesting unusual electrochemical behavior, probably derived from the potential-dependent electric double layer structure typical to the ionic liquid. Electrodeposition of Cd was performed by potentiostatic electrolysis and the deposits were characterized by X-ray diffraction, energy dispersive X-ray analysis and scanning electron microscopy.

Electrodeposition of selenium (Se) in an amide type hydrophobic room temperature ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) containing SeCl 4 as a Se source in the presence of excess chloride on a glassy carbon electrode was studied at 25 and 50 • C. Raman spectroscopy showed SeCl 4 in BMPTFSA with excess chloride forms an octahedral chlorocomplex of [SeCl 6 ] 2-. The reduction of [SeCl 6 ] 2-to Se and that of Se to Se(-II) were observed by cyclic voltammetry. Electrodeposits obtained by potentiostatic electrolysis were confirmed to be metallic Se by energy dispersive X-ray, X-ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy.
